Functions

void cv::fastcv::FFT (InputArray src, OutputArray dst)

Computes the 1D or 2D Fast Fourier Transform of a real valued matrix. For the 2D case, the width and height of the input and output matrix must be powers of 2. For the 1D case, the height of the matrices must be 1, while the width must be a power of 2. Accepts 8-bit unsigned integer array, whereas cv::dft accepts floating-point or complex array.

void cv::fastcv::IFFT (InputArray src, OutputArray dst)

Computes the 1D or 2D Inverse Fast Fourier Transform of a complex valued matrix. For the 2D case, The width and height of the input and output matrix must be powers of 2. For the 1D case, the height of the matrices must be 1, while the width must be a power of 2.
